Was Sikandar Lodhi a "kind monarch"?
"Islam and Hindu Dharma are both equally acceptable to God if followed with sincerety."
This detail is reported in "History of the Delhi sultanate" by M.M. Syed. It appears on page 176, and can even be seen on google books. The book gives further examples of his "kindness" such as:
"..he frequently razed temples to the ground and erected mosques in thier place, as evidenced by his behaviour at Mandrail, Utgir, and Narwar. At Mathura he prevented hindus from bathing in their sacred ghats or having themselves shaved.
The stones of broken hindu idols were given away to butchers (of cows) to be used as weights."
Interestingly, Sikandar Lodhi's mother was a hindu!
